I read over some of the articles that granny posted. Most of them all say that very small amounts of THC can somehow reduce the buildup of fat in the arteries.

I'm wondering if the effects of the heart rate increase you get from smoking pot is similar to the heart rate increase you get from common exercise. I know also that weed relaxes your muscles allowing for increased blood flow to you extremities, so I'm sure that cant be bad for you.

Either way, it would be really awesome to burn more calories while smoking, that is, considering you can resist the munchies.
